Este documento es el resultado de una revisión teórica de los diferentes modelos e investigaciones realizadas en torno al concepto de los estilos de aprendizaje y su intervención en el desarrollo de ambientes virtuales de aprendizaje. En un primer momento se presenta una breve reseña del surgimiento de los estilos de aprendizaje a nivel teórico, se describen sus principales autores, modelos, y las categorías que los conforman. Posteriormente se presentan los diferentes estudios realizados a partir del uso de diversos modelos en el diseño y evaluación de ambientes virtuales de aprendizaje, así como de sistemas hipermedia adaptativos. Al final del documento se describen los avances del proyecto que se ha venido desarrollando en la Universidad del Norte (Barranquilla, Colombia), el cual pretende establecer los efectos de un modelo de enseñanza virtual centrado en los estilos de aprendizaje en el desempeño académico de un grupo de estudiantes universitarios.
* This essay was carried out thanks to the financial support of the Instituto Colombiano para el Desarrollo de la Ciencia y la Tecnología (COLCIENCIAS).Abstract-Based on the concept of adaptive hypermedia, the webCT platform was used to design a learning virtual environment that would allow students' interaction of different support materials with their usual styles of learning. GA Latin Square design was used to determine the role that environment and learning styles, along with intrinsic motivation, played on academic performance, navigation patterns, and number of visits to the support materials.The study showed an important difference in academic performance in favor of the Balanced group. Intrinsic motivation was the main explicative factor for the differences found beyond learning styles. The conclusion was that there are differences in the way of using the objects of learning, and that there are differentiated patterns to access the support material, depending on the students' learning styles.
This article studies the endogenous and exogenous causes of the high prices of US medical goods and services and their relationship with the international health displacement of their patients through the economic and normative analysis of the legal provisions of national medical care. It was found that the deregulation of health sector agents has caused an increase in direct and indirect costs with very detrimental effects on patients. This article contributes new knowledge since it identifies market concentration and federal deregulation as motivators for the displacement of patients to other destinations for medical purposes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
